I had a sailboat with the old original 1986 trailer. The trailer was rated at 1200 lbs, which is what the boat hull was supposed to weigh leaving the factory. Later found that my boat actually weighed just over 1700 lbs. In my case...it was the tongue that had developed a downward facing bow. If you know what the rig weighed new, I'd take it to a weigh station and see what it weighs now. Is that trailer up to the load after long service? |

Does galvanized welding really exist or are you referring to an axle galvanized after it was welded? Welding temperatures are higher than the melting point of zinc, and zinc is consumed or highly altered during any welding process. It also produces toxic fumes that cause weld fume fever. Galvanizing is done after welding, either on virgin metal, or a redip after welding repairs. Zinc melts at 419.5, and iron at 1535. Steel is iron with other elements added, and can be heated to over 2,000 degrees for tempering purposes. At that temperature, the zinc would be burned off, or assimilated into the metal.
